Jack got down on his hands and knees and looked under the cot. “There’s a trapdoor there,” he whispered to Amos, “and somebody’s knocking.”
“A trapdoor in the bottom of a ship?” asked Amos.
“We won’t question it,” said Jack, “we’ll just open it.”
They grabbed the ring and pulled the door back. Through the opening there was only the green surface of the water. Then, below the surface, Lea appeared.
“What are you doing here?” whispered Amos.
“I’ve come to help you,” she said. “You have gotten two-thirds of the broken mirror. Now you must get the last piece.”
“How did you get here?” asked Jack.
“Only the shiny surface of things keeps us apart,” said Lea. “Now if you dive through here, you can swim out from under the boat.”
“And once we get out from under the boat,” said Amos, “we can climb back in.”
“Why should we do that?” asked Jack.
“I have a plan,” said Amos.
“But will it work even if the grey man is already in the garden of violent colors and rich perfumes, walking past the pink marble fountains where the black butterflies glisten on their rims?” asked Jack.
“It will work as long as the silver-white unicorn guards the fragment of the mirror,” said Amos, “and the grey man doesn’t have his hands on it. Now dive.”
The prince dove, and Amos dove after him.
“Will you pipe down in there,” called the jailer without opening his eyes.
In the garden the grey man, with sunglasses tightly over his eyes and an umbrella above his head, was indeed walking through violent colors and rich perfumes, past pink marble fountains where black butterflies glistened. It was hot; he was dripping with perspiration, and his head was in agony.
He had walked a long time, and even through his dark glasses he could make out the green and red blossoms, the purple fruit on the branches, the orange melons on the vines. The most annoying thing of all, however, were the swarms of golden gnats that buzzed about him. He would beat them away with the umbrella, but they came right back again.
After what seemed a long, long time, he saw a flicker of silver white, and coming closer, he saw it was a unicorn. It stood in the little clearing, blinking. Just behind the unicorn was the last piece of the mirror.
“Well it’s about time,” said the grey man, and began walking toward it. But as soon as he stepped into the clearing, the unicorn snorted and struck his front feet against the ground, one after the other.
“I’ll just get it quickly without any fuss,” said the grey man. But when he stepped forward, the unicorn also stepped forward, and the grey man found the sharp point of the unicorn’s horn against the grey cloth of his shirt, right where it covered his bellybutton.
“I’ll have to go around it then,” said the grey man. But when he moved to the right, the unicorn moved to the right; and when he moved to the left, the unicorn did the same.
From the mirror there was a laugh.
The grey man peered across the unicorn’s shoulder, and in the piece of glass he saw not his own reflection but the face of a young woman. “I’m afraid,” she said cheerfully, “that you shall never be able to pick up the mirror unless the unicorn lets you, for it was placed here by a wizard so great and so old and so terrible that you and I need never worry about him.”
“Then what must I do to make this stubborn animal let me by? Tell me quickly because I am in a hurry and have a headache.”
“You must prove yourself worthy,” said Lea.
“How do I do that?”
“You must show how clever you are,” said Lea. “When I was free of this mirror, my teacher, in order to see how well I had learned my lessons, asked me three questions. I answered all three, and these three questions were harder than any questions ever heard by man or woman. I am going to ask you three questions that are ten times as hard, and if you answer them correctly, you may pick up the mirror.”
“Ask me,” said the grey man.
“First,” said Lea, “who is standing just behind your left shoulder?”
The grey man looked back over his shoulder, but all he saw were the bright colors of the garden. “Nobody,” he said.
“Second,” said Lea, “who is standing just behind your right shoulder?”
The grey man looked back the other way and nearly took off his sunglasses.
